Mobile terminal
Disclosed herein is a mobile terminal including a first frame, a second frame slidably movable from the first frame in a first direction or a second direction opposite to the first direction, a slide frame movable with respect to the second frame in the first direction or the second direction, a flexible display comprising a first region coupled to the first frame, a second region coupled to the slide frame, and a third region disposed between the first region and the second region, the third region being bent in a manner of surrounding the second frame, and a first magnet positioned on a rear surface of the second frame and configured to provide magnetic force to pull the slide frame or the flexible display. The mobile terminal may allow the size of the screen to be adjusted as needed, thereby satisfying both portability and usability.
1. A mobile terminal comprising:
a first frame;
a second frame slidably movable with respect to the first frame in a first direction or a second direction opposite the first direction;
a slide frame movable with respect to the second frame in the first direction or the second direction;
a flexible display comprising a first region coupled to the first frame, a second region coupled to the slide frame, and a third region disposed between the first region and the second region and bent around the second frame; and
a first magnet positioned on a rear surface of the second frame and configured to provide magnetic force to pull the slide frame,
wherein the first magnet is extended in the first direction such that a polarity of the first magnet is same along the first direction.
2. The mobile terminal of claim 1 , wherein the first magnet has a tape shape extending in the first direction.
3. The mobile terminal of claim 2 , wherein the first magnet is positioned in a center of the second frame in a third direction, the third direction being perpendicular to the first direction.
4. The mobile terminal of claim 2 , wherein the first magnet comprises a plurality of first magnets spaced apart from each other in a third direction, the third direction being perpendicular to the first direction.
5. The mobile terminal of claim 1 , further comprising:
a second magnet positioned on a front surface of the slide frame to face the first magnet and having a polarity opposite the polarity of the first magnet.
6. The mobile terminal of claim 5 , wherein:
the first magnet has an N-pole and an S-pole arranged side by side in the third direction perpendicular to the first direction; and
the second magnet has an S-pole and an N-pole arranged side by side in the third direction.
7. The mobile terminal of claim 6 , wherein:
a width of the N-pole of the first magnet in the third direction corresponds to a width of the S-pole of the second magnet; and
a width of the S-pole of the first magnet in the third direction corresponds to a width of the N-pole of the second magnet.
8. The mobile terminal of claim 1 , wherein:
the second frame is formed through injection molding of which magnetic powder is mixed with an injection molding material; and
the second frame is integrated with the first magnet.
9. The mobile terminal of claim 1 , further comprising:
a rolling plate attached to a rear surface of the flexible display to support the flexible display, the rolling plate containing a metal material.
10. The mobile terminal of claim 9 , wherein the rolling plate comprises:
a plurality of support bars extending in a third direction and arranged side by side in the first direction, the third direction being perpendicular to the first direction, and
wherein at least a portion of the plurality of support bars contains a metal material.
11. The mobile terminal of claim 9 , wherein the second frame comprises:
a side portion arranged at an end facing in a third direction, the third direction being perpendicular to the first direction; and
a slide rail arranged inside the side portion, and
wherein the rolling plate comprises:
a plurality of support bars extending in the third direction and arranged side by side in the first direction; and
a slide hook protruding from an end of each of the plurality of support bars.
12. The mobile terminal of claim 11 , further comprising:
a slide hook protruding from an end of the slide frame and inserted into the slide rail to move along the slide rail.
13. The mobile terminal of claim 9 , wherein the rolling plate comprises a magnetism shielding sheet.
14. The mobile terminal of claim 1 , further comprising:
a low-friction layer attached to at least one of a surface of the second frame or a surface of the slide frame.
15. The mobile terminal of claim 14 , wherein the low-friction layer contains polytetrafluoroethylene.
16. The mobile terminal of claim 1 , further comprising:
a tension wire having one end coupled to the slide frame and another end coupled to an end of the first frame facing in the first direction; and
a tension roller coupled to the second frame, the tension wire being wound around the tension roller.
